Perhatikan gambar di samping! Tentukan Volume bangun ruang di samping!

Diket :

• d = 14 cm

• r = 7 cm

• T tabung = 20 cm

• T kerucut = 44 cm – 20 cm

= 24 cm

Dit :

• V gabungan = ?

• V gabungan = V tabung + V kerucut

• V gabungan = π × r² × t + ⅓ × π × r² × t

• V gabungan = (22/7) × 7 × 7 × 20 + ⅓ × (22/7) × 7 × 7 × 24

• V gabungan = 22 × 7 × 20 + 22 × 7 × 8

• V gabungan = 3.080 + 1.232

• V gabungan = 4.312 cm³
